WHY CALCSUITE

Works offline. Every tool except live exchange rates works with no
connection, and the currency converter keeps the last synced rates so it
still gives you an answer on a plane or underground.

Shows its working. Each calculator explains how the result was reached, so
you can trust the number or verify it.

Calm about ads. Banner ads only on tool screens, with a hard daily cap on
full-screen ads. A one-time Remove Ads purchase clears them for good.

Fast to use. Opens instantly, remembers your favourites and recent tools,
and searches all 18 tools from a single box.

Private. Your calculations stay on your device. No account needed.
